Sorry an error in my above post. The two messages that flash on screen between the all-purple screen and the Ubuntu splash screen are:
MP-BIOS bug: 8254 timer not connected to IO-APIC ata3: softreset failed (device not ready) The all-purple screen lasts for about 20 seconds. The two messages above last for about 3-5 seconds. Still seems to boot fine ie without the stripey / herringbone effect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1234429 Title: 1002:5975 [Dell Inspiron 1501] vertical coloured lines / herringbone pattern on startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1234429/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
